We, too, are finding out. We did last time and hubby felt like it helped him bond with our baby better, knowing it was our son in there!
We are very nosy (if the sonographer knows then we want to know!) and practical people and I'm almost annoyed that I can't get any of the sales bargains now, but have to wait another 5 weeks...
I must admit I would be worried about hubby having to dash out to buy baby clothes (or even use the washing machine to wash our sons bits lol) in case I had to stay in hospital for whatever reason!
Very much each to their own though and I started off this pregnancy thinking I wouldn't mind not finding out this time, but now the time can't go by fast enough!
On a related note: FiL does not want to know till the birth so we cannot tell anyone in hubby's family or announce it on Facebook - How annoying!
